Regression issue from long time ago:
Custom field sets are displayed twice on CiviCRM event participant registration.
Steps to reproduce (tested on Demo site):
- Create custom field set, linked to Participant (Event) - Any -
- Add custom field
- Select register new event participant. Custom field gets displayed (Correct).
- Select event type. Same custom field gets fetched and displayed again. Total 2 (Incorrect).
- Fields will be duplicated.
